/lucee/form.cfm error in console (single-mode)

Am running Lucee 6.2.0.321 with single mode, then at lucee\tomcat\webapps\ROOT\WEB-INF\lucee is empty.
getting 404 for http://domain.com/lucee/formtag-form.cfm
Not able to proceed with cfform tags, getting the same console error.
While switching to multimode, am getting that missing file & console error get resolved, able to submit it.

confirmed, that’s currently broken Jira
